HQST 12V 100Ah Lithium Iron Phosphate LiFePO4 Battery with LED Display - 10 Year Warranty

Backed by an industry-leading 10-year warranty and lifespan, the HQST 12V 100Ah LiFePO4 battery is a reliable power solution for a wide range of applications—RVs, trailers, trolling motors, boats, off-grid cabins, and home backup systems.

Built with Grade A cells and an upgraded Battery Management System (BMS) featuring low and high-temperature cut-off protection, this lithium battery delivers safe, consistent performance. It also supports up to 4 batteries in series and 4 in parallel, allowing for easy system expansion to a powerful 20.48 kWh home battery bank (up to 16 batteries total). Plus, the integrated LED display keeps you informed of remaining capacity, voltage, and charge/discharge current—no more guesswork.

Important Reminders:

● 1. Ensure the battery terminals are securely fastened. Loose terminals can lead to heat accumulation and potential battery damage.

● 2. After a full discharge at a continuous 100A, avoid immediate recharging at 50A, as this may trigger high-temperature charging protection.

● 3. Optimal charging involves a 20A current for our lithium-ion battery. While the maximum charging current stands at 50A, exceeding this limit can result in a shortened battery lifespan.

● 4. How to Calibrate Screen Display:

● 1) Discharge the battery to 0%.

● 2) Use a compatible LiFePO4 battery charger or solar charge controller to fully charge the battery.

Key Features

10-Year Lifespan & Upgraded BMS

The HQST 100Ah LiFePO4 battery is built to last, backed by 10-year product support and long service life. It features an advanced built-in BMS with 20+ layers of protection, including low and high-temperature cut-offs. This protects your battery during charging and discharging, even in extreme conditions. Plus, all internal battery cells are UL tested and certified to ensure maximum safety and reliability.

Upgrade to a More Powerful LiFePO4

HQST lithium batteries outperform traditional lead-acid batteries with a superior lifespan of up to 10 years, compared to just 1 to 3 years for most lead-acid options. Weighing only 22 lbs, this 12V LiFePO4 battery is lighter, more compact, and delivers more power than standard lead-acid batteries. Plus, it comes with an integrated BMS for enhanced safety—something SLA batteries simply don’t offer.

Series & Parallel Connections for Expandable Power

The HQST 12V 100Ah lithium battery supports both series and parallel configurations. Easily build a 24V, 36V, or 48V battery bank with series wiring, or expand your capacity to 12V 200Ah, 300Ah, or 400Ah through parallel connections. For larger setups, you can link up to 16 batteries in series and parallel to create a powerful 20.48 kWh home backup system—ideal for power outages or hurricane season.

Optimal Charging & Discharging Performance

The HQST 12V 100Ah LiFePO4 battery delivers full 100% usable capacity, unlike traditional SLA batteries that only offer about 50%. With a continuous discharge current of up to 100A, it’s powerful enough to run most household appliances. For best results, charge at 20A, with a maximum charging current of 50A. Recharge easily using a LiFePO4 charger, a solar panel system (must with a charge controller), or a DC-DC charger.

Wide Range of Applications

The HQST lithium battery includes a built-in LED display that shows real-time power capacity, voltage, and charging/discharging current—taking the guesswork out of your setup. Perfect for RVs, trailers, trolling motors, boats, off-grid cabins, and home backup power during outages or hurricane season.

Why Isn’t the LED Display Accurate?

If the LED display isn’t showing the correct readings, you can try calibrating it by following these steps:

1. Discharge the battery completely to 0%.

2. Use a compatible LiFePO4 battery charger or solar charge controller to fully charge the battery.

If the issue persists, please contact us at sales@myhqsolar.com for further assistance.

What are the charging voltage and charging current for this battery?

The max. charging voltage is 14.6V and the max. charging current is 50A. For optimal charging performance, we highly recommend adjusting the voltage to 14.2V-14.6V and using a 20A charger.

Does this 12V 100Ah battery offer low-temperature protection?

Yes, it does. When the temp reaches -5℃~5℃, this lithium battery will stop being charged, and when the temp reaches -25℃~15℃, the battery will stop discharging. Ideal for harsh and rugged environments. It also has high temperature protection.

Does this battery have low voltage cut-off protection?

Yes, it does. When the discharge voltage is lower than 11.1V, the battery will shut off automatically.

Can I use my lead acid battery charger to charge the lithium battery?

We recommend using a lithium battery compatible AC to DC charger to charge LiFePO4 batteries, or else cause irreversible lifespan damage to the batteries. You can also charge these batteries using compatible solar charge controllers and solar panels.

Will the battery come with the terminals? And if not, what's the size of the connector terminals?

Yes, it comes with two M8 screw terminals.

Can I charge the battery directly using a solar panel?

No, you should not connect the solar panel directly to the battery. When charging this battery with a solar panel, make sure to use a solar charge controller (either PWM or MPPT) between the panel and the battery. Directly connecting the panel to the battery could result in unstable solar power, which may damage your devices.
